I’m in panic mode! I only bought this chicken yesterday (Tesco BBQ prepacked) and I fancied some for lunch. I didn’t heat it up because I normally enjoy it cold with a salad. (The package does specify can be eaten hot or cold). Half way through, I noticed the use by date was yesterday!! I stopped eating straight away, but now I’m worried. I’m 19+5 weeks. How worried should I be???
